MAX JASPER, or BERLIN, GERMANY.

SAFETY-CLOSURE FOR CONTAINERS OF INFLAMMABLE LIQUIDS.

Specification of Letters Patent.

Patented July 28, 1914.

Original application filed September 18, 1912 Serial No. 720,940. Divided and this application filed December 17, 1912. Serial No. 737,175.

To all whom it may concern Be it known that I, MAX JASPER, a citizen of Germany, residing at Berlin, Germany, have invented a new and Improved Safety-Closure for Containers of Inflammable Liquids, of which the following is a specification.

This invention relates to a safety closure for bottles, jars, cans and similar containers of inflammable liquids, the present application being a division of an application filed by me September 18th, 1912 under Serial No. 720,910.

The closure is adapted to be fitted into the mouths of such containers as are provided with but a single ingress and egress opening, so that it permits the pouring in as Well as the pouring out of the liquid. The construction should be such that the closure cannot be readily removed by unauthorized persons. So also the closure should eflectively prevent the flame from striking inward, for

which purpose it should be made to eifectively conduct the heat generated, which latter purpose is rendered more difficult by the location of the closure within the mouth of the container.

In the accompanying drawingrFigure 1 is a side view partly in section of part of a container embodying my invention; Fig. 2 a similar view of a modification, and Fig. 3 a similar view of a still further modification.

Referring more particularly to Fig. 1, the neck 10 of a bottle, jar, can or other container for inflammable liquids is provided with a head 11. Within, neck 10, there'is housed a foraminated member 12, shown to be composed of a small meshed wire tube or elongated net open at the top. Means are provided for firmly securing the tube 12 to head 11 and for abstracting the heat from tube 12. These means consist of an annular metal cap 13 secured to the upper end of tube 12 and extending from the interior of the bottle head 11 around the outer face of the same. At its top, cap 13 is provided with an annular bead 141- that accommodates a packing ring 15 and also prevents the liq;

uid from splashing while being poured out. In order to secure the cap to the bottle, there is provided a stopper 16 having a bail 17, on which turn a pair of arms 18, the bent ends of which enter a pair of diametrically opposed apertures 19 formed in the cap and bottle. The safety device can thus only be detached by withdrawing arms 18 from apertures 19.

In Fig. 2,the cap 13 is secured to the bottle.

I to form an annular trough 24 adapted to collect drippings of the inflammable liquid. In this way, the burning liquid cannot reach the hand of the operator, so that a resulting involuntary-release of the bottle and a consequent explosion are avoided.

It is obvious that changes may be made in the construction of the safety device withvent-ion.

I claim:

1. A bottle, adapted to contain inflammable liquids, provided with a heat conductive cap that extends from the interior of the bottle head downwardly over the outer face thereof, toinclose said head, said can constituting a stopper-seat, a stopper'adapted to engage said seat, a heat conductlve cribrate member that is attached to the cap and depends from the inner end thereof into the neck of the bottle, and means for irremovably securing the cap to the bottle head,

whereby a withdrawal of the cribrate memher from the interior ofthe bottle is preposition of the stopper. N

2.. A bottle ada ted to contain an infiam mable liquid com ined with a heat conducthe cap that snugly embraces the exterior of vented in the closed as well as in the open 75 out departing from the spirit of my in the bottle-head and extends downwardly head and a removal of the cap and cribrate into the interior of said head, a heat c0nmember from the bottle without destroying ductive cribrate member depending from the cap-securing means is rendered impossible. 10
